Cardiac CT angiography is an inter-arterial pathway to study the prevalence and short-term results of elderly patients whose right coronary artery originates from the left Valsalva sinus

Abstract

Purpose: Anomalies of coronary artery origin (ACAOS) in the contralateral Valsalva sinus are common in 1% of common
patients. And 0.4-0.7% of the imaging population. Inter-arterial disease course (IAC) is thought to be related to sudden heart
attacks. Death, especially in young athletes involving abnormalities in the left coronary artery that originated mainly in the
right sinus IAC and Valsalva. The prognosis of Valsalva left sinus and right coronary artery abnormality (R-ACAOS) with
IAC is as follows. Not sure. We aim to evaluate the prevalence and short-term prognosis of R-ACAOS through cardiac
computed tomography Angiography (CCTA).
Methods: This is a single-center retrospective cohort study of 625 consecutive patients who were suspected of being referred
to CCTA. Coronary artery disease (CAD) from January 2012 to December 2017. 10 cases of R-ACAOS were found using
IAC. Each case was matched with two controls of age, gender, CAD severity, cardiovascular risk factors, and history of
revascularization. Measure the results of MACE, including fatal or non-fatal MI, coronary revascularization, or all-cause
death.
Results: The prevalence of R-ACAOS and IAC was 1.6%. The average age of the cases and controls is 65 years. 70% male. so
many The average ± SD time of MACE was 13 ± 15 months and 29 ± 22 months, respectively. The incidence of MACE in the
case and control group was 50% and 40%, respectively. The hazard ratios were: 1.25 (0.055-2.84), P=0.59).
Conclusion: In elderly patients, the short-term prognosis of R-ACAOS with IAC is similar to that of the control group. manage
These patients should be similar to those without R-ACAOS
